FIELD OF THE INVENTION

The invention relates generally to systems and methods for controlling systems with moving parts. In particular, the invention relates to systems and methods for controlling, for example by remote activation, an actuating mechanism of a blind system to open or close blinds of that blind system.

SUMMARY OF THE INVENTION

In accordance with the present invention, systems and methods for controlling blinds are described. These systems and methods may be carried out using a remote device (e.g., a remote control, a computer, a mobile phone, etc.). The system and methods may provide for an outer housing (e.g., a tube) having an inner cavity sized to include various components. Such components may include: a motor having a motor shaft configured to rotate about a first axis; a programmable circuit; a power source configured to power the motor; and a magnetic clutch. Any of these components are optional.

The outer housing may couple to a head rail or any part of blinds such as a gear box or an attachment attached to a gear box. The attachment may receive a motor or a motor may be substituted for a motor that couples to the gear box. A shaft of the motor may be controlled to rotate a certain distance based on a rotational counter or a predetermined time period, and the time period of rotation may be control by a user activating one or more buttons on a remote control. Rotation of the shaft may tilt open or close blinds. The motor may be disengaged by a user so that the user may manually open and close blinds.

The outer housing may connect to a tilt mechanism using any one of various means, including male and female connectors and cavities configured to receive tilt mechanisms. The outer housing may connect to a gear box. Such a connection may utilize a cavity in the outer housing from receiving a shaft from the gear box, or a shaft formed with the outer housing that is received by a cavity formed with the gear box.

A motor may be formed inside a gear box, and a control device may connect to the gear box to deliver power and/or control instructions to the motor. A spring may be used to disengage a gear from the motor and to engage that gear with another gear so that a user may manually tilt open and close blinds without the operating the motor. The spring may be replaced by a mechanical or electrical device such as but not limited to a solenoid, or a simple mechanical male and female tongue and a lip that would lock to each other.

DETAILED DESCRIPTION OF THE INVENTION

Various aspects of the invention are described below. It should be apparent that the teachings herein may be embodied in a wide variety of forms and that any specific structure, function, or both, being disclosed herein is merely representative. Based on the teachings herein one skilled in the art should appreciate that any aspect disclosed may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways.

Aspects of the invention may feature mechanical, electric and/or other systems for controlling the position of blinds commonly used in windows and doors. It is to be understood, however, that the inventive aspects described herein and understood by those skilled in the art can be applied to all types of blinds and other systems with moving parts.

The present invention offers various advantages over previous systems and methods for controlling blind systems. For example, one aim of the present invention relates to ease of installation and use. As one of skill in the art will come to understand, the inventive aspects of the present invention permit a user to install various implementations of the invention without having to dismantle or substantially modify the blind system. In accordance with several embodiments, a user need only attach that embodiment's inventive blind control device to existing actuators of typical blind systems. Attachment may require only having to slide an embodiment's inventive blind control device over a hook or other feature, or into a cavity without any need of cutting or otherwise modifying the blind control device. Users of the various inventive blind control devices will benefit greatly by avoiding the significant investment of time (e.g., in relation to user installation) and/or money (e.g., in relation to professional installation) required to install previous blind control devices. Certain inventive blind control devices are also significantly smaller than previous blind control devices, and can be attached to a blind system to appear as if the respective blind control device was part of that blind system.

Further benefit is created by the power delivery aspects of various embodiments. For example, use of batteries as opposed to hardwiring to electrical conduits behind a wall, permit a user to quickly install those embodiments without any need to hire an electrician. Furthermore, the batteries are easily accessible, and can be changed by removing a cap. The ease of removing the batteries is contrasted to other systems that require a trained personal to remove and reinstall the blind in order to replace the batteries, or to hardwire a power source. The ease of battery removal reduces the cost of maintenance significantly and allows an operator to continually use the remote option without abandoning it due to maintenance cost.

Various embodiments described herein permit a user to easily program and control that embodiment's blind control device using wireless data/signal transmission or by activating physical components (e.g., a manual switch, push button, etc.) on the blind control device. For example, programming and control may occur at/from a wireless device (e.g., a mobile computing device, a computer or router capable of transmitting wireless signals, a remote control device). Signals/data may be received from and/or sent to those wireless devices using RF, IR, Bluetooth, or other wireless technologies. The present invention contemplates appropriate software (e.g., applications for displaying a user interface, software for controlling a motor or other drive mechanism of certain blind control devices) and hardware (e.g., processors, sensors, switches, etc.) at the wireless devices and the blind control devices to carry out and manage the programming and control functionality described herein.

One of skill in the art will appreciate various control commands, including commands for rotating a motor axle (described in more detail below) in one direction to open blinds a desired amount and rotating the motor axle in the other direction to close the blinds a desired amount. For example, when a user presses any of various buttons on a wireless device, a signal may be sent to a processing unit of the blind control device, which in turn controls the rotation of the motor shaft to open or close the blinds. Pressing one button/switch and releasing it may result in the blinds opening or closing to a predetermined position (e.g., opening to let in the most light or closing to block the most light). Pressing another button and releasing it may result in the blinds opening or closing only for the period of time in which the button was push. Under this scenario, a user would have to press and hold the button until the blinds have opened or closed a desired amount. Pressing another button may control any number of blind systems and subsets of blind systems. Pressing yet another button may indicate a predefined operation (e.g., the opening or closing of the blinds at a later time or under certain conditions). One of skill in the art will appreciate that user-activated buttons can be replaced by a computer interface where a user selects presently-desired or scheduled operations.

One of skill in the art will further appreciate various programming commands using the same buttons/switches and/or user interfaces.

Programming and control of certain inventive blind control devices may alternatively involve sensors and/or processing components that receive input relating to light, sound, motion, position of blinds, temperature, time or other properties/characteristics, and then use received input to control a blind system. Such sensors and/or processing components would be positioned within and/or on an external surface of a respective blind control device.

In accordance with one example, a blind control device may include or use information from a sensor to determine when sensed ambient light (e.g., sunlight) exceeds a threshold brightness level (e.g., a brightness level determined by a user-programmable or preset value), and may then control a blind system to open or close its blinds. By way of another example, a blind control device may include a sensor that determines if sensed ambient temperature exceeds or falls below a threshold temperature level (e.g., a temperature level determined by a user-programmable or preset value), and may then control a blind system to open or close its blinds based on the determination. A blind control device may also or alternatively respond to sound (e.g., a human voice, including the user-programmable or preset words “open” and “close”) or to motion (e.g., a human entering a room).

A blind control device may also or alternatively control a blind system to open or close its blinds based on the time of day (e.g., as determined by an internal time-keeping component, or as determined by a signal received from an external device such as a clock, remote control with clock, etc.). Or, the blind control device may control a blind system to open or close its blinds based on a predefined time period since an event as determined by an internal or external time-keeping component or device (e.g., since the blinds opened or closed, since a sensed amount of light exceeded a threshold level of light, etc.).

One of skill in the art will appreciate that the sensor information regarding temperature, light, motion and sound, and the timer information may be obtained by the blind control device from remote sensors and timers not physically attached to the blind control device. Receipt of such sensor and timer information may be obtained using various wireless signal transmission techniques described herein in relation to remote wireless devices.

For a better understanding of certain aspects and features of the present invention, attention is drawn to the following Overview.

Overview

While the details of the embodiments of the invention may vary and still be within the scope of the claimed invention, one of skill in the art will appreciate that the figures described herein are not intended to suggest any limitation as to the scope of use or functionality of the inventive aspects. Neither should the figures and there description be interpreted as having any dependency or requirement relating to any one or combination of components illustrated in those figures.

Aspects and features of the invention are designed to operate in relation to mechanical and/or electrical systems with movable components. In accordance with various embodiments described herein, aspects and features of the invention are designed to manipulate one or more vertical and horizontal louvers/slats (generally referred to herein as “blinds”) of a blind system by transferring rotational motion from a motor to an actuator mechanism of the blind system that opens and closes the blind louvers/slats. Such actuator mechanisms may include, without limitation, tilt mechanisms (e.g., with a wand or baton attached thereto), ropes, chains and other components of blind systems that open and close blind louvers/slats.

It will be understood that the terms “blind” or “louver” or “slat” may refer to individual vertical or horizontal members of blind systems which are capable of being opened, closed or otherwise adjusted. The term “tilt mechanism” may refer to an actuating mechanism that enables the opening, closing or other adjustments to the blinds. It will be understood that ‘blind system” is described herein as a single blind system. However, the teachings herein may apply to control of several blind systems, each with a blind control device, and each controlled by the same remote control device.

Blind Control Device

Attention is now drawn to FIGS. 1A-C, which depict different orientations of a blind control device 100 having various components described below. The blind control device 100 depicted in FIG. 1 may take various configurations within the scope and spirit of the invention. For example, the disclosed system may be configured to include an outer housing 105 of any shape, including cylindrical, rectangular, triangular, polygonal, spherical, cubic or other geometric shapes. The outer housing 105 may be covered in any sort of design and material and color. The blind control device 100 may further include a blind connector component 110, an anti-rotation feature 115, one or more magnets 120 a-b, a motor connector component 125, a motor 130, a motor housing 135, a rotation-locking pin 140, a circuit board 145 or other suitable processing/control component with a control interface 146, a first battery connector 150, one or more batteries 155 (e.g., of any size or type and in any configuration including a specially-made batteries) or other suitable power source, a second battery connector and end cap 160, a power lead 165, a screw 170 and a pin hole 175. Each of these components and their relationships to each other are described in more detail below with respect to various features.

Attention is turned to FIG. 2 though FIG. 9, which depict various components from FIGS. 1A-C that may be used to cause the blind connector 110 to rotate in relation to force provided by the motor 130. FIG. 2, for example, depicts a first portion 200 of the blind control device 100 of FIGS. 1A-C.

FIGS. 3A-C depict several orientations of the blind connector component 110. As shown, the blind connector component 110 may include a magnet receiving section 311 and a blind connection section 312. The magnet receiving section 311 may include a cavity 313 that is configured to receive magnet 120 a. Adhesive, friction, a mechanical fastener, or another method of attachment may be used to hold magnet 120 a in place within the cavity 313 formed by the magnet receiving section 311. Blind connection section 312 may include a receiving slot 314 disposed to receive a hook, screw a pin or other feature of a blind system (not shown) that, when rotated, manipulates the blinds to open, close or perform some other movement.

FIGS. 3D-E depict a blind connector component similar to the blind connector component 110 of FIGS. 3A-C. In contrast to the blind connection section 312 of FIGS. 3A-C, which is depicted as having a “male” shape, FIGS. 3D-F depict a blind connection section 312 having a “female” shape.

FIGS. 3F-I depict blind connector components without the magnet receiving section 311. Instead, FIGS. 3F-I depict blind connector components with a motor connection section 327 that couples directly to the motor 130 with use of the magnetic clutch 120 a-b and associated holders 311 and 125

FIGS. 3J-N depict several orientations of the blind connector component with a cavity 315 for receiving a male tilt shaft from a blind system. FIGS. 3O-Q depict an adapter that attaches to a shorter tilt shaft. FIGS. 3R-S depict an adapter for attaching to a female tilt adapter and the blind connector component of FIGS. 3J-N or FIGS. 3D-E.

In an alternative configuration shown in FIGS. 3T-V, a first blind connector component is configured to attach directly to a tilt box using any method of attachment—e.g., receiving a screw that screws into the tilt box, adhesion via glue/tape, magnetic coupling, insertion of structural elements into the tilt box, integral formation with the tilt box, etc. As shown, the alternative blind connector component of FIGS. 3T-V includes an opening 316 for receiving any part of the outer housing 105, the motor 130 and/or other components described herein. Also shown are structural elements 317 t that include pin holes 318 and can also be threaded. Structural elements 317 t are configured to insert into and through structural openings 317 w of a second blind connector component shown in FIGS. 3W-Z, which attaches to the first blind connector component and to blind control device 100 (e.g., with or without the blind connector component 110). The second blind connector component shown in FIGS. 3W-Z further includes a lip section 319 that fits into an opening of the outer housing 105 and that attaches to the outer housing 105. The attachment may be accomplished using any of the techniques described herein in relation to other features of invention, including adhesion and mechanical features.

FIGS. 18A-C depict several orientations of a blind connector component 1810. As shown, the blind connector component 1810 may include a motor connection cavity 1813 that is configured to receive a motor shaft (e.g., motor shaft 631 of FIG. 6). One of skill in the art will appreciate that the motor connection cavity 1813 may take any shape or form to couple to the motor shaft. In cases where the motor shaft is a female configuration, the cavity 1813 may instead take the form of a male counterpart for that female configuration. Adhesive, friction, a mechanical fastener, or another method of attachment may be used to hold magnet motor shaft in place within the cavity 1813.

FIGS. 4A-C depict several orientations of the motor connector component 125. As shown, the motor connector component 125 may include a magnet receiving section 426 and a motor connection section 427, each having a particular geometric shape. One of skill in the art will appreciate that these geometric shapes can take the form of any suitable geometric shape (e.g., a star shape or ‘D’ shape for the motor connection section 427), and that the shapes shown in the figures are merely included to illustrate certain aspects of the invention. The magnet receiving section 426 may include a cavity 428 that is configured to receive magnet 120 b. Adhesive, friction, a mechanical fastener, or another method of attachment may be used to hold magnet 120 bin place within the cavity 428 formed by the magnet receiving section 426. Motor connection section 427 may include a receiving cavity (not labeled) disposed to receive a motor shaft 631 (shown in FIG. 6 and described in more detail below).

FIGS. 5A-B depict two magnets 120 a and 120 b, respectively. When magnetically coupled, under certain pressure constraints, the magnets 120 a-b operate as a magnetic clutch that transfers rotational motion from the motor 130, through the motor connector component 125 and the blind connector component 110, and on to an actuating mechanism (e.g., a tilt mechanism) of a blind system (not shown). Pressure between the magnetically attracted surfaces of the magnets 120 a-b is maintained while the motor 130 provides rotational motion until the actuating mechanism of the blind system cannot rotate (i.e., until the blinds controlled by the actuating mechanism are fully closed or open), at which point magnet 120 a stops spinning and magnet 120 b continues to spin until the motor 130 stops. Once the motor 130 stops, the magnets 120 a-b once again magnetically couple to each other.

One of skill in the art will appreciate that a friction clutch could be used by replacing the magnets with a suitable material. One of skill in the art will appreciate alternative embodiments that do not use a magnetic or frictional clutch, where that motor 130 could connect directly or through other components to the blind connector component 110. In accordance with some of these alternative embodiments, a fractional number of rotations of the blind connector component 110 (or the motor shaft 631 described below) may be tracked. Based on the fractional count of rotations, the blind control device could, using preprogrammed information, determine the position of the blinds in relation to a fully-closed position and a fully-open position. Based on a determined position, the blind control device could stop rotation of the blinds when they reach the fully-closed and fully-open position. Although other clutch systems can be used, the magnetic clutch embodiment is preferred due to cost and ease of operation.

FIG. 6 depicts the motor 130. The motor 130 may be any sort of motor, including an electric motor. As shown, the motor 130 may include a rotatable motor shaft/axle 631, power leads 632, and fastening features 633 a-b. As shown and previously described, the motor shaft 631 may be configured to be inserted into the motor connection section 427 of the motor connector component 125. The motor shaft 631 is shown to have an external gear that may be inserted into the motor connection section 427. The motor shaft 631 is also shown to have an external gear having a particular geometric shape that mates with the shape provided by the motor connection section 427 or the motor connection cavity 1813. One of skill in the art will appreciate that the geometric shape of the external gear may take the form of any suitable geometric shape (e.g., a star shape or ‘D’ shape), and that the shapes shown in the figures are merely included to illustrate certain aspects of the invention. One of skill in the art will further appreciate that an internal gear may be used for the motor shaft 631, and that the motor connection section 427 (or some other component connected to the motor connection section 427) may be shaped to compatibly couple to the internal gear.

Adhesive, friction, mere insertion, a mechanical fastener, or another method of attachment may be used to hold the motor connector component 125 in place around the motor shaft 631. When the motor shaft 631 rotates upon delivery of electrical current via power leads 632, the rotational energy may be transferred to the blind connector component 110 through the motor connector component 125 and the magnets 120 a-b, which operate as a magnetic clutch as previously described. Power leads 632 operate to deliver power the motor 130 from batteries 155 via the circuit board 145 of FIGS. 1-2. Fastening features 633 a-b may include adhesive, insertable mechanical components, cavities to receive insertable mechanical components, or other methods for preventing the motor from spinning inside the motor housing 135. The motor housing 135 made alternatively be made integral with the tube itself.

One of skill in the art will appreciate that the motor 130 may operate to control an actuator of a blind system without the magnetic clutch. For example, the motor shaft 631 could directly attach to the actuator of the blind system or to some intermediate component between the actuator and the motor shaft 631 (e.g., connector 1810).

One of skill in the art will appreciate that the motor 130 may operate with a rotational count mechanism (not shown) that counts a number of rotations of the motor. Such a rotational count mechanism may be integral with or connected to the motor or circuit board 145. By knowing the number of rotations of the motor shaft 631, the motor shaft can be instructed not to over-rotate the actuator of a blind system, thereby preventing damage to the blind system or blind control device, and also reducing unnecessary power use of the batteries 155. Knowing the number of rotations will permit the blind control device or a remote control device to track start and stop positions of the motor shaft for further control of the motor shaft and additional precision in relation to the operation of the blind control device.

FIG. 7 depicts the motor housing 135. As shown, the motor housing 135 forms a cavity 736 configured to receive the motor 130. The motor housing 135 includes fastening features 737 a-b, which compliment fastening features 633 a-b of FIG. 6. The motor housing 135 also includes a locking section 738 with pin holes 739 a-b that are configured to receive pin 140, which may be inserted through the outer housing 105 and through the pin holes 739 a-b to prevent the motor housing 135 from rotating. One of skill in the art will appreciate that preventing the motor housing 135 from rotating may be accomplished using various methods other than using the pin 140, including methods that use adhesive, other mechanical fasteners and features (e.g., screws, clips, tongue and groove), or other techniques understood by one of skill in the art.

When the motor 130 is inserted into the motor housing 135, the power leads 632 a-b may extend into and/or beyond the locking section 638. Upon insertion of the motor 130 into the motor housing 135, the leads 632 a-b may reside on opposite sides or the same side of an inserted pin 140. The leads 632 a-b are configured to connect to respective power terminals 847 a-b of the circuit board 145 shown in FIG. 8 and described in further detail below.

As previously mentioned, FIG. 8 depicts a circuit board 145. As shown, the circuit board 145 includes the control interface 146, power terminals 847 a-b and power terminals 848 a-b. Power terminals 847 a-b may connect to leads 632 a-b, respectively. Power terminals 848 a-b are described in more detail later. Although not shown, the circuit board 145 may include any number and type of sensor (using any of the sensor technology described herein), database, processing, display, counting or other computing or electrical components.

The functionality of the control interface 146 may include programming of functional instructions, transmitting/receiving of signals/data to/from other components (e.g., sensors, motors, wireless devices, processing components that carry out instructions stored in memory, etc.), and controlling of the motor shaft 631. Accordingly, the control interface 146 may include an interface for programming and controlling the operation of the blind control device 100, including the motor shaft 631. The control interface 146 may further include an interface for sending and receiving signals. Signals received by the control interface 146 may indicate different types of information, including a direction or position of the motor shaft 631, a fractional number of times the motor shaft 631 has rotated in one or more directions, a position of the blinds (e.g., in relation to a minimum and maximum rotation position), a sensed temperature level, a sensed light amount, or a sensed motion.

The control interface 146 may comprise a push switch that, when pushed, will pair the device 100 with a remote control, or with one or more buttons on the remote control. The remote control may then instruct the circuit board 145 (e.g., one or more processing and control components thereon) to control the operation of the motor 130 to open or close blinds of a blind system. One of skill in the art will appreciate that such a push switch may be replaced by a signal transceiver and a signal processor that operate to receive a wireless signal and process it in accordance with the methods described herein to control the motor 130.

Although not shown, the circuit 145 may include a processor operable to process information described herein (e.g., sensor information, user instructions, etc.). That processing component may execute instructions stored in memory to control the operation of the motor based on the information.

Attention is now turned to FIG. 9, which depicts a different orientation of the first portion 200 previously described in relation to FIG. 2 and other figures. FIG. 9 depicts leads 632 a-b and terminals 847 a-b, which are respectively coupled together to deliver power to the motor 130 and/or to structurally join the circuit board 145 to the motor 130, which may be fastened to the motor housing 135 as previously described. The circuit board 145 may also be fastened to the locking section 738 of the motor housing 135 using adhesive, other mechanical fasteners and features (e.g., screws, clips, tongue and groove), or other techniques understood by one of skill in the art.

FIG. 10 depicts a second portion 1000 of the blind control device 100 of FIGS. 1A-C. As shown, outer housing 105 includes the circuit board 145, the first battery connector 150, and the one or more batteries 155. FIG. 10 also depicts the power lead 165, which attaches to power terminal 848 b (not shown) of the circuit board 145. The power lead 165 may also operate to structurally reinforce the position of the circuit board 145 in relation to other components like the first battery connector 150. In additional or alternatively, the circuit board 145 may be fastened to the first battery connector 150 using adhesive, soldering other mechanical fasteners and features (e.g., screws, clips, tongue and groove), or other techniques understood by one of skill in the art.

As shown by the combination of FIG. 10 and FIG. 11, a positive terminal of one battery 155 contacts a spring 1151 of the first battery connector 150, and power is delivered from the battery, through the spring 1151 and to power terminal 848 a of the circuit board 145 via power lead 1152 of the first battery connector 150. FIG. 11 also shows a flat wall 1153 of the first battery connector 150 that is configured to permit the power lead 165 to extend through the space inside the outer housing 105 that the first battery connector 150 occupies. The power lead 165, which is depicted in FIG. 12, may be fastened to the first battery connector 150 using any of the techniques described herein or known in the art. Alternatively, the power lead 165 could terminate near the spring, and a second power near power lead 1152 could connect to power terminal 848 b of the circuit board 145 (configuration not shown).

As shown in FIG. 12, the power lead 165 may include a surface area 1266 that couples to the power terminal 848 b. As shown by the combination of FIG. 12 and FIG. 13, which depicts a third portion 1300 of the blind control device 100 of FIGS. 1A-C, the power lead 165 may further include a screw hole 1267 configured to receive screw 170.

FIG. 14 depicts the second battery connector 160. As shown, the second battery connector 160 may include a spring 1461 that contacts a negative terminal of one battery 155 (as indicated in FIG. 13), a screw hole 1462 configured to receive the screw 170, and a receiving section 1463 that forms a cavity 1464 for receiving and securing a rod/baton or other suitable object to extend the tube for easier reach. For example, a rod is shown in FIG. 20 and designated as 2079. The rod 2079 may be compression fit into the cavity 1464 or otherwise coupled to second battery connector 160 using adhesive, a mechanical fastener (e.g., a screw threaded through opening 175), or other technique.

The batteries 155 may be removed after the second battery connector 160 is disengaged from the outer housing 105. Removal of the batteries 155 may be carried out without any need to remove the blind control device 100 from the blind system to which it is coupled. The ease of removing batteries in this fashion is yet another advantage of certain aspects of the present invention over previous blind control systems.

The batteries 155 may be of any type in relation to size, shape and voltage. The batteries 155 may also be rechargeable. Although not shown, a solar charger may be connected to or integral with the device 100 to recharge the batteries 155. Such a charger could wrap around or otherwise attach to the outer housing 105, or could be adapted to removably connect to the device 100 and the batteries 155 for the purpose of charging the batteries 155.

Attention is now turned to FIGS. 15A-B and 16A-C, which collectively depict different embodiments of the invention that prevent the blind control device 100 from spinning freely during operation, and which ensure that rotational motion from the motor 130 is directed to an actuating mechanism of a blind system that manipulates the blinds to open, close or perform some other movement.

FIGS. 15A-B depict the anti-rotation feature 115 at different orientations. As shown in FIGS. 15A-B, the anti-rotation feature 115 includes a tongue section 1516, and a perimeter section 1517 (e.g., in the shape of a ring) that forms an opening 1518. The opening 1518 may be sized to fit over part of the blind connector component 110. The perimeter section 1517 may include a lip section that fits into an opening of the outer housing 105 and that attaches to the outer housing 105. The attachment may be accomplished using any of the techniques described herein in relation to other features of invention, including adhesion and mechanical features.

FIGS. 16A-C depict different adaptors 1680 a-c that attach to various blind systems. As shown, each adaptor 1680 a-c includes a respective attachment feature 1681 with an opening 1683 that receives a portion the blind system, thereby securing the adaptors 1680 to the blind system. Once the adaptors 1680 are secured, the blind control device 100 may be connected to the blinds system, and the tongue section of the tongue component 115 may be inserted into an opening 1684 formed by a structural element 1682.

The anti-rotation feature 115 and adaptor 1680 operate to prevent the outer housing 105 and any component securely attached to it (e.g., the motor housing 135 via pin 140 or other attachment technique described herein) from rotating when the motor shaft 631 rotates. The anti-rotation feature 115 and adaptor 1680 ensure that the rotational motion from the motor shaft 631 is not transferred to the outer housing 105, and is instead transferred through the motor connector component 125, through the magnetic clutch (e.g., magnets 120 a-b), through the blind connector component 110, and to the actuating mechanism of a blind system. During rotation initiated by the motor shaft 631 and before the blinds are fully closed or open, the force applied by the tongue component 115 when it is inserted into the adaptor 1680 does not break the magnetic or frictional bond of the magnets 120 a-b, thereby ensuring that the rotational motion of the motor shaft 631 is transferred by the magnetic clutch (e.g., magnets 120 a-b) to other components for rotating an actuating mechanism of a blind system.

FIGS. 16D-H illustrate additional adaptors. For example, the adaptors in FIG. 16D-F are similar to the adaptor in FIG. 16C. In FIG. D, a vertical wall is removed from attachment feature 1681 c to form attachment feature 1681 d.

In FIG. 16E, structural element 1682 c is replaced with structural element 1682 e, which couples to attachment features 1681 e at coupling structure 1687 e via some sort of coupling method (e.g., a pin, screw, snap, etc.) Such a coupling method permits the structural element 1682 e to move relative to and the attachment feature 1681 e and independent of any movement or non-movement by the attachment feature 1681 e. By contrast, structural element 1682 c and attachment feature 1681 c of FIG. 16C are fixed to each other, which does not permit either one of those features to move independent of the other feature.

FIG. 16F is similar to FIG. 16E except a lower structural element 1682(i) is coupled to an upper structural element 1682(ii) at coupling structure 1688 f via some sort of coupling method, and the upper structural element 1682(ii) is fixed to the attachment feature 1681 f. Such a coupling method permits the lower structural element 1682 f(i) to move relative to and the upper structural element 1682(ii) and independent of any movement or non-movement by the upper structural element 1682(ii). By contrast, structural element 1682 e FIG. 16E does not consist of two parts.

The adapters in FIGS. 16G-H illustrate a variation of the adapter in FIG. 16A. By comparison to the adapter in FIG. 16A, the adapters of FIGS. 16 G-H include vertical walls 1686 g and h, respectively, which comprise holes 1686 g and h, respectively. Holes 1686 g and h are configured to receive pins or some fastening feature on a blind system, or may by alternatively configured to receive a fastener (e.g., a screw) that passes through the holes 1686 g and h before coupling to a blind system.

One of skill in the art will appreciate different designs of the feature 115 and the adaptor 1680 that are within the spirit and scope of the invention. For example, the feature 115 and/or adaptor 1680 may be formed on or attached to the blind system or the blind control device 100 in any manner consistent with the disclosure herein.

Example of Blind System & Blind Control Device

FIG. 17 depicts a blind system 1790 that may include blind louvers 1791, blind tilting mechanisms 1792 and a blind actuating mechanism 1793. The blind actuating mechanism 1793 may be coupled to a blind control device 1700 with an exposed or internal sensor 1701 (e.g., a sensor like those previously described herein). The blind actuating mechanism 1793 may be configured to receive rotational motion from the blind control device 1700, and then transfer that rotational energy, through intermediary components, to the tilting mechanisms 1792. A remote device 1702 may send signals to control the rotational motion of the blind control device (e.g., to control the rotational motion from a motor (not shown) of the blind control device).

FIG. 21 depicts a remote control device 1899 for sending instructions to the blind control device 100 for operating the motor 130. The instructions may be received by a receiver (e.g., control 146 or other component on the circuit board 145), and used by a processor or similar component to control the operation of the motor 130.

The remote control device 1899 is preferably digital, but may also be analog. The remote control may include a timer that tracks time and causes the motor 130 to operate based on the tracked time. For example, the timer may cause the motor 130 to cause blinds to open in the morning and close at night. The digital version of the remote control device may include control buttons 1802 for programming the operation of one or more blind control devices 100. Such programming may specify times of operation, degrees to which blinds are opened, and other operations. Also, such programming may be stored locally at the blind control device 100 or on the remote control device.

The control buttons may also include forward and reverse buttons 1803 and 1806 for control the operation of the blind control device 100 and control to direction of rotation for the motor 130. The control buttons may also include a round (or any shape) button 1804 that may select particular blind control devices 100 that will receive particular programming instructions. Selected blind control device 100 may be indicated by number or other designation on the display 1801.

The control buttons may also include group buttons 1807 (e.g., three group buttons 1-3) that allow a user to select various blinds to operate at the same time (eg, blinds 1, 4 and 8). Each button may be programmed for particular groups, and when activated will control only that group. Having group control eliminates the need for individually selecting each blind control device 100 to execute a particular operation.

FIGS. 22-27 depict various implements for connecting the motor 130 directly to a gearbox inside a tilt box. Direct connection of the motor 130 to the gearbox may be accomplished by omitting various components from FIG. 1. For example, direct connection of the motor 130 to the gearbox may occur without any use of components 110, 120 or 125 of FIG. 1.

FIGS. 25A-C illustrate different orientations of a gear box/attachment (e.g., with motor) combination. As shown, a gear box 2501 includes a gear 2502 which translates mechanical force from gear 2205. Gear 2205 rotates upon application of a mechanical force from a motor 2530, which is transferred from the motor 2530 to the gear 2205 via a suitable coupling. The motor 2530 may be powered and control by a power source and control circuitry in control device 2500. Elements 2231 and 2232 may couple to each other to deliver power to the motor 2530 and/or deliver control signals to the motor 2530. Power and control signals may alternatively be delivered via other connected areas.

Element 2231 may also or alternatively be configured to receive rotational force from element 2232 (and control device 2500. Such rotational force may be transferred to the gear 2505.
